Answer: Option D.

Cyclins are proteins that regulate the cell cycle at molecular level.

Explanation:

Cell cycle refers to series of activities that take place in the cell leading to replication of DNA and division of cytoplasm to give two daughter cells. Cell cycle are regulated by a set of proteins called cyclins.

Cyclins are group of proteins the bind and activates cycling dependent kinases enzymes in order to control cell progression through the cell cycle.

Answer:

D; cyclins

Explanation:

Cyclins as the name implies undergo a constant cycle of synthesis and degradation during cell division. When cyclins are synthesized, they act as an activating protein and bind to Cdks forming a cyclin-Cdk complex. This complex then acts as a signal to the cell to pass to the next cell cycle phase.

Which mutation is an example of an insertion mutation?
Burka [1]

Answer:

d. AAU CCG CAU UGG A​

Explanation:

A mutation is any change or alteration to the sequence of a gene. There are, however, different types of mutation depending on how it occurs in the gene. One of these types is INSERTION MUTATION as mentioned in this question. Insertion mutation is a type of mutation in which one or more nucleotide base is added to the sequence, hence, changing the reading frame of the original sequence.

In this question, the original mRNA sequence is given as: AAU CCG CAU GGA.

An insertion mutation will cause nucleotide base(s) to be added to this sequence, which will be noticed by an increase in number of bases in the sequence.

The correct answer is: AAU CCG CAU UGG A​. In this mutated sequence, nucleotide "U" has been added to the sequence.

When does the cell cycle start at? When does it end?
disa [49]

The D period refers to the stage between the end of DNA replication and the splitting of the bacterial cell into two daughter cells. In cells with a nucleus, as in eukaryotes, the cell cycle is also divided into three periods: interphase, the mitotic (M) phase, and cytokinesis.
